Electrostatics

The formal and partial charges can be
summed up and turned into a vacuum electrostatics potential map. The user
must input the PDB code in capitals and then press the button. This will
put a surface over the molecule demonstrating the positive and negative
potentials. A ramp is also placed at the bottom of the screen and the
potentials on the surface can be modified according to it by using Ctrl + middle
mouse button. If the user wishes to get rid of the map and surface they
can press the Remove button. Once again the PDB code must be in the
entry.
